Excellent work
Don’t be surprised if they don’t even notice all your hard work, people who just drive their cars without a care for its condition are oblivious to such things.
I once spend all day on the wife’s car which was filthy inside and out and hadn’t been washed for six months, she was away for the weekend, when she returned I left it a week or so and asked her what she thought and she said she hadn’t noticed, the difference was night and bloody day!
